I'm no LampizatOr pusher and I think that I get your point. Recently I've heard Thoress integrated amp and the guy who makes them was very specific that he uses one specific tube because it does the job better than any other and that changing it in his circuitry is rather pointless.
All this I get and I also am able to grasp that Nelson Pass pulled of things in his F7, which most other manufactures would probably sell for five times more. There are engineers who have - I don't know how to call it - a deeper understanding of the subject or they simply know more, that's how I see it. Not sure, maybe you are one of them, I've heard some very nice things about your goods as well.
Still, I don't see myself as delusioned person as far as audio goes. I share my office with a journo who reviews at least several usually expensive products per month. Point being, over the years of working near the man I've heard way too many things to gush over audio products. I'm past this, new toys became a routine. But subjectively speaking I haven't yet heard a DAC which would be better than GG we share, everything else we've tried gets murdered and there were some fancy sources here alright. Not sure what exactly, but Fikus has to do something right in order to pull this off. I can't explain this in any other way.
